Applicationfiled October 7,1904. Serial No. 227,543.

Be it known that I, FRIEDRICH LUDwIe BARTELT, soap and chemical manufacturer, residing at 3 Kensington' Place, Brislington, Bristol, in the county of Somerset, England, have invented new and useful Improvements in Apparatus for Preparing Bleaching Liquor, 0 which the following is a specification. In the aocompanyingdrawings, Figure 1 Fig. 2 is a plan view, and Fig. 3 is a sectional elevation of the same. i

The object of this invention is to provide a convenient well-arranged apparatus for preparing bleaching liquor to beused for various purposesin the arts-such, for instance, as in' steam-laundries and places where only small quantities of bleaching liquor are re- .quired. i I It is customary at this time 'touse bleaching liquor in steam-laundries for the purpose of bleaching the clothes or fabrics after they are washed, and it is essen tial that the bleachi ing bleaching liquor is by electrolysis, and as small floor-space. The partsfshou convenient of access and-theworking should in liquor employed shall be of such a character that .while it properly cleanses and bleaches it shall not act injuriously u on the fabrics.

convenient apparatus has been upon the.

For the reason that no suita 1e and market to prepare bleaching liquoras required by small users it has been usual to urcha se bleaching liquor ready prepared in.

arger orsmaller quantities and store it. until required for use. The storing of bleaching liquor has obvious disadvantages consequent upon the nature of the article, and it has been thought that if this liquor could be made onthe premises in such uantities as may be necessary, say, for a sing e washing and with out difiiculty a great saving in many Ways could be effected.

A common and convenient way of producall large laundr es as well as bleach-works nowadays use some motive power to drive the machinery that is employed in the busi-- ness it has been thought that advantage could be taken of this motive power toproduce the electricity which is necessary for the electrolytic treatment .of chemical solutions in order to provide the'bleachirig liquor. In

order, then, to carry out this object, an apparatus must be provided which will be complete in itself and which will occupy only a also be be as far as possible automatic. To this'end the apparatus should comprise a source of electricity, a solution-tank, an electrolyzer, and a product or liquor tank, to which'may be added, so as to make the apparatus complete in itself, a storage tank or box for the chemical and various details which will be more particularly defined hereinafter.

' .Witha view to make the working automatic the solution-tank should be at a higher level than the liquor-tank, the electrolyzer being placed in such a position with respect to-the other two that the solution acting by gravity shall pass through the electrolyzer on its way to the product or liquor tank. This arranigement will necessitate the use of a raise 'latformfo'r the solution-tank, and u on t e sameplatform' Ifix the source of e ectricity. Ithus have a s ace below, which"- I can utilize as a place 0 storage for-the 'chem'ical. I Referring now to the drawings, A may be said to represent the platform, which, however, may be inone with the storage-chamber B. This chamber will be provided with a door or doors conveniently placed for the insertion and withdrawal of the chemical.

C is a chamber, in which the source of electank may be seen and by which the filling of 5 the tank may be regulated. This indicator may take the form of a board with transverse divisions marked upon it 'to'indicate' so many allons of Water, according to the amount '0 thechemical' put In other words, the strength of the solution may be lated by means of this indicator. ,1

eat the bottom ofhe tank E two or more outlet pipesG of various diameters are provided, each with a cock, and all these. ipes r enter a common pipe Hinconnection wit the 'to of the electrolyzerl. The object of provi ing two or more outlet-pipes of various sizes, each of which may be opened or closed independently of'the other, is that the, flow of too the electrolyte from the tank E to the elec-- trolyzer may be accuratelyregulated, aceording to the strength of the. liquor required by opening one outlet-pipe and closing another '5 or by opening both of the pipes. .It is extremely diiiicult to regulate the flow from the tank E to the electrolyzer by a single outlet-pipe, as it is hard to turn the cock therein to a predetermined point to permit the pro )er Io flow of the liquor from the tank E to the e ectrolyzer.

The 'electrolyzer I use may be of any convenient construction so long as the electro-' lyte is made to take acourse while in the I electrolyzer during which it may remain a long time more or less in contact with the electrodes, and thus insure corresponding production of the bleaching liquor.

In the solution tank, preferably in the cornor behind the indicatonboardis provided a float J of any convenient construction,

adapted under certain circumstances to close one or more circuits. Thus it may close a bell-circuit K and an electrolyzing-circuit L.

When the level of the solution in the tank E descends below a certain point, the float J "closes both these circuits, so that the bell is rung to call the attention of the attendant,

' and at the same time the switch is operated to cut off the current to the electrolyzer, as-

otherwise the continuing current would produce a liquor of a character the use of which would be very detrimental to the well-being of the clothes into contact with which itmight be brought.

The labor employed in a laundry is not likely to be of a highly technical character, and it is therefore necessary to employ means such as described to prevent accidents of the kind indicated.

M is the bleaching-liquor tank. The various tanks will be provided with hin 'es or other covers, so that the parts may be kept clean and the escape of gases pre- 15 vented as far as possible.

ed to close the bell and electrolyzing-circuits and break the main circuit under certain conditions, and outlets of various diameters from the solution-tank to the electrolyzer,

all substantially as described.

' 2. An apparatus for preparing bleaching liquor comprising a solution-tank, a float therein, an electrolyzer at a lower level than the tank, and a bleachingdiquor tank below the electrolyzer in combination with a source of electricity in circuit with the electrolyzer, a bell-circuit and an electrol Zing-circuit including a switch adapted to be closed by the float, all substantially asdes'cribed 3. Apparatus for preparing bleaching li nor comprising a platform, a solution-tan on said platform and. a source of electricity .mounted on said platform, a storage-chamreparing bleaching ber situated under said platform, an electrolyzer below the level'of the solution-tank, and a bleaching-liquor tank below the electrolyzer, a main circuit between the source and the electrolyzer, a switch in this circuit, a float in the solution-tank, and an electro lyzing-circuit including a switch adapted to be closed by the float, all substantially as de- V scribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
